A solid electrolyte includes stabilized or partially stabilized zirconia, and a gas sensor provided with the solid electrolyte. A change rate of a crystallite diameter for at least one of a cubic phase and a tetragonal phase in crystal particles constituting the solid electrolyte configured by a fired body after performing an annealing treatment, before and after heating the solid electrolyte from room temperature to 1200° C., is 10% or less. The solid electrolyte preferably includes partially stabilized zirconia.
